Abstract
637,000. Rotary engines; centrifugal pumps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 9, 1948, No. 7250. Convention date. March 12, 1947. [Classes 110(i) and 110(ii)] A not-gas engine, or a compressor for a refrigerating apparatus, of the liquid-ring type comprises blade wheels 13, 14 which rotate on the axis of a shaft 12, varying chambers formed by the liquid ring and the blades communicating with one another by way of oblique channels 18. For an engine, the gas is heated and expanded in the wheel 13 and passes through channels 18, which contain heat regenerators 19, to the wheel 14 where the gas is again compressed, the connected chambers in the two wheels being out of phase with one another. Heat is supplied by a burner 29 heating projections 30, and cooling done through fins 31 over which flows a coolant. The liquid 20 is partly contained in a housing 7 and partly in a housing 1, passing through apertures 27 to the bottom of 1 where it is heated or cooled according to whichever side of a central partition it lies on. Discs 21, 22, provided with impeller blades, cause the liquid to flow into collecting channels 23, 24 and conduits 25, 26 leading back into the rotating housing 7. The power shaft 3 is itself rotated to start up the engine. The housing 7 rotates and through an internal gear 16, the two blade wheels 13, 14 rotate. The axis of the shaft 12 rotates around the axis (produced) of a fixed shaft 2 and thus the blade wheels 13, 14, besides rotating on their own axis, also gyrate within the housing 7. A gear wheel 5, carried on a shaft 6 on a housing 10, rotates around the shaft 2. The gear 5 meshes with an internal gear on the housing 7, and a fixed gear 4. The regenerators 19 are heated by the hot expanding gas, which heat is absorbed from the regenerators by the compressed working fluid flowing back from the wheel 14. The speeds of the various rotating parts are given in the Specification. The liquid forming the ring may be of high density, low vapour pressure, low melting point, high boiling point and a low viscosity. It may be formed of an alloy or metal salts in an engine, especially where air is the working fluid; examples are bromine and iron compounds. If an oxygen-free working fluid is used, such as helium, argon, hydrogen or nitrogen, the liquid may be potassium, sodium or an alloy of potassium and sodium. For a refrigerating apparatus, mercury or a bromine compound may be used. In a modified arrangement, the power shaft 100, Fig. 4 (not shown), is coupled by external gears to the engine gearing.
